摘要:
Abstract(S‐2‐amino‐5‐(aminooxy)pentanoic acid (L‐homocanaline, HCan), a structural analogue of lysine, contains a reactive alkyloxyamine side chain and is therefore considered to react chemoselectively with carbonyl compounds by forming a kinetically stable oxime bond. The chemical synthesis ofL‐homocanaline starting from protected glutamic acid derivatives is described. Two orthogonally protected homocanaline derivatives were synthesized and their use in standard SPPS procedures was exemplified for the synthesis of a chemoselectively addressable cyclic peptide for use in TASP design. Moreover, the wide range of applications of this unique building block was demonstrated for the chemoselective ligation of an unprotected disaccharide to a HCan containing model peptide resulting in a chimeric glycopeptide structure. © 1998 European Peptide Society and John Wil
